If you are looking at measuring the power out of a power supply or a pixel controller or whatever this will mean a DC clamp which are more expensive. They also usually have a zero feature on them as it's usual that they have DC offset with them.

Personally i like anything with "FLUKE" written on it, but then again I have an employer who buys mine…

I would suggest checking out the local electrical wholesalers and/or buying one from Jaycar or such before buying direct from China, that way you can be certain that it is approved and shouldn't blow up in your hand etc
